Be it known that we, IRVINE M. NOBLE, a citizen of the United States, residing at Indianapolis, Marion diana, and lVALTnR E. Goss'mno, a citizen of the United States, residing at Indianapolis, arion county, and State of Indiana, have invented and discovered certain new and useful Improvements in Methods of and Tools for Securing Connecting Parts of Battery-Plates, of which the following is a specification.

The object of our said invention is to provide a method and means for securing plateconnector posts of storage batteriesto the battery cover in an expeditious and inexpensive manner, the particular character of con nection between said posts and cover being that illustrated in our application for Let ters Patent No. 187,873, filed August 23, 1917. The present invention resides largely implement employed.

Referring to the accompanying drawing which is made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is a view showing one corner of'a battery cell in section with a plate connector post secured in the cover as shown and described in our above mentioned ap plication, and by the use of the tool, and

the process forming the subject matter of this application, the tool being shown in the position it occupies in the process, complete, and the joint between the part formed, and

Fig. 2 a section through the body of the tool.

In said drawing, the portion marked A represents the battery cover; B the plate connector post; C the plateconnector; D one of the battery plates; E the wooden separator separating the negative plates; F the body of the cell; G the battery box; and H the seal around the outer edge of the battery cover, all of which parts may be of a well proved construction.

The tool for forming the joint between the. plate-eonneeter post and the cover, consists of a body 10 having a tapered socket 11 in its lower end of a size audform corresponding to the. size and form desired for the upper end of the post. Just. above the inner end of said socket said body 10 is pro- Specification of Letters Patent.

county, and State of Inaineter of the positive and they known or any ap vided with annular perforations 12 the perforation 12 the inner end of foration l3 cutting into said perforation 12 from the other side of the body ata point a very short distanceabove its inner end. A bracket 14 is attached to one body adjacent to the outer end of the pen foration 12 and a gas torch or burner 15 is mounted in said bracket with its nozzle or dlscharge end arranged to direct the flame into perforation 12. The gas burner is connected with a mixing chamber 16, and a gas supply pipe 17 may lead from any source of supply, such as an acetylene gas tank, as will be readily understood. The body 10 is provided with a stem 18 of appropriate dimensions, and a handle, or cross bar, or pin, 19 may be inserted in a transverse perforation near the upper end of said stem for the purpose of manipulation and handling of the tool.

While we have shown a gas burner as a means for heating the tool, it will be understood, of course, that any means found appropriate may be employed for this purpose, such as appropriate electr' al means, if found more convenient.

In operation the parts are assembled by inserting the post B through the aperture in the battery cover A until the annular flange 20 bears against the under face of said cover, when said post fits tightly in said aperture. Sealing material of common character may be provided in said aperture if found necessary or desirable.

The tool is then pressed down over the top of the post, it being designed to be of slightly. less diameter than the normal dipost at a point near the cover so that the lower end of the socket 11 impinges upon the surface of the post a short distance before the end of the tool reaches said cover. The body 10 being hot, causes the metal of the post to soften or fuse sutiiciently so that a quantity of the metal will be forcedinto each annular recess around the top edge of the aperture in the cover and form the annular flange 21. filling said reor form a flange overhanging the top edge of the aperture. according to whatever type of joint is to be formed.

Because of the (.llill'zlCtQl of the metal of which the post is composed, and the high Patented May 6, 191s; Application filed November 26, 1917, Serial No. 204,028. Renewed September 25, 191 8. Serial No. 255,703."

Itssinner lower corner may be formed slightly rounded, as shown, and by turning the tool as it is forced down a neat and perfect joint is'formed, and one proof against the leakage of the electrolyte.

Having thus described our .said invention what we claim. as new and desire to secure by Letters Patent, is:

- 1. The method of securing the connector post of battery plates to the battery cover which consists in inserting said post through an aperture in said cover then heating the part of the post'above the cover to slightly fuse the metal and pressing the metal down around the edge of the opening in said cover, substantially as set forth. i 2. A tool for use in securing the connector posts of battery plates to ing a socket adapted to fit over the top of said post and impinge against the surface- 7 the cover of the I battery cellcomprising a body member hav-' thereof at a point slightly above the cover, means for heating said member and means for pressing said member down on said post to force metal from its periphery down around the edge of the opening in said cover, substantially as set forth.

3. A tool for securing plate connector posts to the covers of battery cells comprising a member with a socket adapted to fit over the top of said post, means for heating said member, means for forcing said member downward on said post, the lower end of said socket at its inner edge being form a flange on said post around the top edge of the opening in said cover, substantially as set forth.

In witness whereof, we have hereunto set our hands and seals at Indianapolis, Indiana this th day of November, A. D., nineteen hundred and seventeen.
